This is a very versatile shutter made by combining the lightweight framing strength, stability and thermal properties of WRC and the tough, durable, economical properties of using a Polymer blade.By using a complete WRC mainframe (top & bottom rails and side stiles) along with reinforced aluminium insert) PVC blades, this creates the perfect all-round solution for inside and out. Other PVC shutters on the market just can’t hold up over time and due to the joining process used with simple screws, they begin to sag very quickly.
